r4175 | acceptthis | 2013-01-26 18:23:37 +0000 (Sat, 26 Jan 2013) | 8 lines improved replacementdeltas+nq a little, still needs work. embrace the menuqc! pr_dumpplatform now includes MENU defs+builtins. swapped search ordering of paks+dirs, so progs.dat will be used instead of pak0.pak/progs.dat. fteqcc slightly more sensible with if statements and void+vector types. fteqcc shows the first line where models are precached/used instead of showing no line at all. fix missing explosions when running qw gamecode. accept channels between 8 and 255. support for sending fitzquake's increased stat limits. ------------------------------------------------------------------------ git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4173 fc73d0e0-1445-4013-8a0c-d673dee63da5
